Taxpayers with reported income under $50,000 and those who did not itemize deductions were excluded.

Discretionary income was defined as the adjusted gross income minus taxes, median housing costs (based on ZIP code and provided by the U.S. Census) and average living costs, such as food, clothes, transportation, health care and child care (as measured by the Bureau of Labor Statistics).
